Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a 360-degree multifunctional filter. Background Technology

[0002] Water filtration is a crucial process in modern industrial production and daily life, used to remove impurities from water and ensure its safety and purity. Traditional pipeline filtration systems typically involve installing a filter screen or device inside the pipe to intercept particulate matter and other impurities in the water.

[0003] However, existing pipeline filtration structures have some significant drawbacks, including but not limited to the following: 1. Significantly reduced water flow velocity: When water flows through the filter screen, due to the narrow water outlet, the water must pass through tiny pores, resulting in a significant reduction in flow velocity or clogging by impurities. This problem is particularly pronounced under conditions of high flow rates or high levels of impurities, affecting the efficiency of the entire system. 2. Filter screen clogging: Over time, various dirt and impurities gradually accumulate on the filter screen, reducing its effective pore size and further decreasing the water flow velocity. In severe cases, it can even cause complete clogging, forcing users to frequently stop the system for cleaning or replacing the filter screen, increasing maintenance costs and operational complexity.

[0004] In view of the above-mentioned technical problems, this application makes improvements. Utility Model Content

[0005] This utility model proposes a 360-degree multifunctional filter, which is connected to a pipe for filtering water flow in 360 degrees. It has a fast flow rate, a large filtration area, and will not be completely blocked in a short time, so it does not require frequent cleaning, thus solving the above-mentioned problems existing in the use of the prior art.

[0006] The technical solution of this utility model is implemented as follows: A 360-degree multifunctional filter includes a tube body, which includes an inlet section, an outlet section, and a filter section. The inlet section is provided with an inlet, and the outlet section is provided with an outlet. The inlet section has a water inlet for communicating with the filter section. A cylindrical filter screen with one end abutting against the water inlet is detachably installed inside the filter section. The side wall of the cylindrical filter screen has a plurality of filter holes. A 360-degree annular water outlet cavity is formed between the inner side wall of the filter section and the cylindrical filter screen. The outlet section communicates with the 360-degree water outlet cavity.

[0007] Preferably, the outer wall of the filter section is provided with an outwardly protruding extension wall, which is used to accommodate a 360-degree water outlet cavity.

[0008] Preferably, the filter section has a drain outlet at the end away from the water inlet, and an end cap is detachably connected to the drain outlet. The end of the cylindrical filter screen away from the water inlet is held against the end cap.

[0009] Preferably, the end cap is integrally formed with a threaded ring seat that is threaded to the inside of the filter section, and the threaded ring seat is used for assembling the end of the cylindrical filter screen inside.

[0010] Preferably, a limiting protrusion is integrally formed on the outer periphery of the water inlet between the water inlet section and the filter section, and the end of the cylindrical filter screen away from the end cap is sleeved on the limiting protrusion.

[0011] Preferably, the water inlet section is provided with a limiting step on the outside of the limiting protrusion ring for supporting the end of the cylindrical filter screen.

[0012] Preferably, an internal threaded hole is provided on the upper side of the water outlet section, and an air vent valve is threaded onto the internal threaded hole.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model greatly increases the effective filtration area for water flow by using a cylindrical filter screen and the annular 360-degree water outlet cavity formed between the inner wall of the filter section and the cylindrical filter screen, thus significantly improving the water flow velocity. Because of the large filtration area of ​​the cylindrical filter screen, it also greatly avoids the problems of easy clogging and the need for frequent cleaning.

[0015] 2. The drain outlet and detachable end cap design make it easier and faster to clean the dirt on the cylindrical filter screen, facilitate backwashing, and also make it easier to install and remove the cylindrical filter screen.

[0016] 3. By setting a limiting protrusion and a limiting step between the water inlet section and the filter section, as well as a threaded ring seat for assembling the end of the cylindrical filter screen, the stability of the cylindrical filter screen during installation is ensured, and the filter screen is prevented from being displaced or deformed due to water flow impact during use.

[0025] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example:

[0027] like Figures 1 to 5As shown, this utility model discloses a 360-degree multifunctional filter, including a pipe body 1. The pipe body 1 includes an integrally formed inlet section 11, an outlet section 12, and a filter section 13. An inlet 111 is provided on the inlet section 11, and an outlet 121 is provided on the outlet section 12. A water inlet 14 for communicating with the filter section 13 is provided on the inlet section 11. A cylindrical filter screen 2, one end of which abuts against the water inlet 14, is detachably installed inside the filter section 13. A plurality of filter holes 21 are evenly distributed on the side wall of the cylindrical filter screen 2. A ring-shaped 360-degree water outlet cavity 131 is formed between the inner side wall of the filter section 13 and the cylindrical filter screen 2. The design allows the cylindrical filter 2 to output water from all 360 degrees. The outlet section 12 is connected to the 360-degree outlet cavity 131. Therefore, water enters from the inlet 111 of the inlet section 11, passes through the outlet 14, enters the cylindrical filter 2, is quickly filtered, and enters the 360-degree outlet cavity 131. Then, it enters the outlet section 12 and flows out from the outlet 121. This invention greatly increases the effective filtration area of ​​the water flow and significantly improves the water flow rate by using the cylindrical filter 2 and the annular 360-degree outlet cavity 131 formed between the inner wall of the filter section 13 and the cylindrical filter 2. Because the cylindrical filter 2 has a large filtration area, it can also greatly avoid the problem of easy clogging and the need for frequent cleaning.

[0028] Furthermore, the present invention provides an outwardly protruding extension wall 132 on the outer side wall of the filter section 13. The extension wall 132 is used to provide a 360-degree water outlet cavity 131 for opening inside. The ratio of the diameter of the 360-degree water outlet cavity 131 to the diameter of the cylindrical filter screen 2 is between 1.3 and 1.6.

[0029] Furthermore, the filter section 13 has a drain port 133 at the end away from the water inlet 14. An end cap 3 is detachably connected to the drain port 133. The end of the cylindrical filter screen 2 away from the water inlet 14 rests against the end cap 3. When the end cap 3 is opened, the end of the cylindrical filter screen 2 away from the water inlet 14 faces the drain port 133, which allows for drainage and facilitates cleaning of the dirt accumulated in the cylindrical filter screen 2. Water can also be introduced from the outlet section 12 in the opposite direction for backwashing. If necessary, the cylindrical filter screen 2 can also be removed for cleaning. It is very convenient and quick to disassemble and assemble.

[0030] In order to ensure that the cylindrical filter screen 2 can be firmly and stably installed inside, a threaded ring seat 31 is integrally formed on the end cap 3 and threadedly connected to the inside of the filter section 13. It should be noted that the end cap 3 is also detachably connected to the filter section 13 through the threaded ring seat 31. In addition, the threaded ring seat 31 is also used for assembling the end of the cylindrical filter screen 2 inside, thereby ensuring the stability of the cylindrical filter screen 2.

[0031] Next, a limiting protrusion ring 15 is integrally formed on the outer periphery of the water inlet 14 between the water inlet section 11 and the filter section 13. The end of the cylindrical filter screen 2 away from the end cap 3 is sleeved on the limiting protrusion ring 15. Furthermore, the water inlet section 11 is provided with a limiting step 16 on the outside of the limiting protrusion ring 15 to support the end of the cylindrical filter screen 2. This structure can ensure the stability of the cylindrical filter screen 2 during installation and prevent the filter screen from being displaced or deformed due to water flow impact during use.

[0032] In this invention, an internal threaded hole 122 is provided on the upper side of the water outlet section 12, and an air vent valve 4 is threaded onto the internal threaded hole 122. The air vent valve 4 itself is an existing structure, therefore its structure will not be described in detail. What this application aims to protect is its optimization effect on the entire system when combined with this invention. The air vent valve 4 allows for the timely discharge of gas accumulated inside the pipe body 1, preventing air blockage and ensuring the safe and stable operation of the system. The air vent valve 4 helps maintain the pressure balance inside the pipe body 1, ensuring that water flows evenly through the filter screen and improving filtration quality. This makes the water flow inside the pipe body 1 more stable.

[0033] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
